When a red flowered pea plant was crossed with a white flowered pea plant, it was found that all plants in the F1 generation carried only red flowers. If these plants are self crossed, i) Find the genotypic ratio that we can expect in F2 generation ii) What is the phenotype and genotype of F1 generation. Draw Punnett square for F2.

Explanation:
ANSWER
RR (Red flower) X rr (White flower) --------------> Rr (F1 generation)
Selfing of F1 :
R r
R RR Rr
r Rr rr
The offspring are: 1 RR - Homozygous Red flowers
2 Rr - Heterozygous Red flowers
1 rr - Homozygous white flowers
Thus the phenotypic ratio is 3 red : 1 white
